Viewport Scrolling: My work is best described as a stack, new things get pushed on to
the stack all the time. With this layout, just push your mouse to the right edge, and
you get more unused real estate for another window. When you finish that task, close the window
and scroll left (popping the last task off the stack).

Window Warping: When you Alt-Tab, the window you chose warps to your current viewport.

No Window Titles: Use the edges or the keyboard, it's one less thing to always see.

No Icons: Why litter on your screen?

Check out the demo below, or just load it up and see what I'm yapping about. ;)
